Hmmm? From cold start up and feel upper radiator hose - aftern thermostat but close to engine end. It should stay quite cold untile thermostat starts to open, then on for a rush of heat toward radiator. If that warms before engine reads a normal and uniform temp then coolant is getting by the thermostat too fast.

New of not, not much should be slipping by and I suspect it is for now - that test would show that.

Sometimes especially if thermostat is mounted vertically they slip their spot while finishing up and allow coolant to pass,
